Hi everyone, just found the forum and have been having a good read, sounds like everyone here enjoys the hobby :)
I start with the bad first - I have 4 gold fish and a couple of snails in a large(ish) wooden barrel with lots of plants against the house on the patio, they have lived quite happily there for 2 years but I want to give them a much larger, and hopefully better home to enable me to put some lillies and taller plants in and ease my consience (excuse the spelling) about the size of their home - and am seeking advice..
I want to build a raised rectangular wooden pond that will be 100cm (or 1m)long, 60cm wide and 58cm high, I have calculated that this will give the 4 goldfish 76.65 gallons (345ish litres) and the a box on both ends to contain plants to provide shade from the sun / frost and cut the wind affect a little.
My question is - do you think this is large enough for 4 goldfish and some snails to live in comfort or should I forget the planters and give them the full 200cm (2m) width which will boost the pond to 153 gallons (694 litres)
I cannot make it any larger due to width constrictions, and it must be a raised pond due to a couple of little un's with no sense of danger !
The pond will be well sheltered with the house in front, a very high wall behind, a fence on one side and will be open to the garden main on the other side..Also the pond will be filtered during summer with a hozelock biofilter/uvc as is the wooden barrel - during winter I remove it all to avooid any frost damage - plenty of plants in there and snails which seems to keep it all oxygentated and the algea under control..
Sorry about the essay of the post - I promise to make it up with some pictures once I start building..
Neither ponds or coldwater fish are my area really so I'm sure someone will be along with better advice later
for what its worth anyway:- Given the normally athletic nature of large common goldfish I'd be tempted to give them a 2m long pond if possible. Also the depth should be at least 90cm to protect them from the cold of winter. Preferably below ground level for the extra insulation. This obviously doesn't mean you cant have your 58cm above ground too, just dig down 40-50cm first.
If you go for the 2m length then either end can be a shallower shelf with some aquatic plants in pots or planters sunk under the water surface. You can get a few plants that grow up from under the water to several feet above. This would give you the extra water volume and swim area whilst allowing you the plants for aesthetics, shelter and water quality.
//edit// no need to delete it! A mod can move it for you
go for the full 2 metres length and as above, dig down a foot or so to make it deeper etc, you can also get a metal grid thing that will mean that the kids can walk over it in complete safety without completely ruining the aesthetics
if you can make a shelf around the pond as well along the back and on the enclosed side to allow planting so that they dont block the view and hide the wall/fence
all this will give you roughly 200 UK gallons to play with which would be the minimum for four goldfish
